How does an object become charged?
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

Students will build upon the model of atomic structure that they developed in the previous investigation. In addition, they will explore the forces involved in maintaining an atom's structure and the effect that introduction into an electric field has on electron distribution. Students will extend their conceptual model of electrostatic interactions to include 1) electron transfer as the mechanism for how an object becomes charged and 2) shifting electron distribution to explain how neutral objects can be attracted to both positively and negatively charged objects. This investigation helps build toward NGSS PE(s): HS-PS1-1 and HS-PS1-3.

How is CO2 affecting our oceans and the organisms that live there?
Unrestricted Use
CC BY
Rating
0.0 stars

In this unit, students will explore the issue of ocean acidification by investigating the effects of increasing carbon dioxide concentrations in air and water, researching the impacts of acidity on living organisms, and developing and revising models of how these components interact. By the end of the unit, models will be used to support student explanations of ocean acidification and to explore and test ideas for decreasing its environmental impact upon Earth's oceans and the organisms that live there. This unit builds toward NGSS PE's: MS-LS2-3 and MS-ESS2-1.

Hurricane Module

Rating
0.0 stars

Students will use the Hurricane Explorer model to explain and predict how the path and strength of a hurricane can change due to sea surface temperature, surrounding atmospheric pressure systems, and proximity to land. Students also investigate real-world case studies to consider and articulate factors that influence the risk and impact of hurricanes including scientific factors (winds, flooding) and social factors (people and infrastructure) on a local and regional scale. Finally, students will explore the effect of rising global temperatures on hurricanes and be able to answer the guiding question: How will hurricane risks and impacts change over the next 100 years?

Hydraulic Fracturing Model

Educational Use
Rating
0.0 stars

Horizontal drilling and hydraulic fracturing are used to produce oil and natural gas from non-porous rock formations. Use this model to explore how such wells are drilled and fractured to release methane from a layer of shale. Like every energy-extraction process, there is the potential for contamination. Use the model to explore how contamination of aquifers might happen during the hydraulic fracturing process.

Hydrogen Bonds: A Special Type of Attraction
Unrestricted Use
CC BY
Rating
0.0 stars

Explore the polar molecule interactions known as hydrogen bonds. Despite the "bond" name, hydrogen bonds are a special type of dipole-dipole interaction. Hydrogen bonds between two molecules (or within portions of a larger molecule) when hydrogen atoms bonded to highly electronegative atoms (such as nitrogen, oxygen, or fluorine) interact with electronegative portions of a different molecule or within the same molecule. Hydrogen bonds are particularly important in stabilizing large macromolecules, such as proteins and DNA.

0.0 stars

Intermolecular attractions are responsible for everything from the temperatures at which substances boil to the power of your immune system in recognizing pathogens and the climbing ability of geckos! Feel the strength of London dispersion and dipole-dipole attractions, explore how intermolecular attractions affect boiling point and solubility, and investigate the special role of hydrogen bonds in DNA. Finally, design your own antibody based on intermolecular attractions.

Intermolecular Attractions and States of Matter
Unrestricted Use
CC BY
Rating
0.0 stars

Explore how states of matter are related to the strength of intermolecular attractions. The three common physical states of matter are solid, liquid and gas. All matter is made up of atoms, which make up molecules. Atoms and molecules can be weakly or strongly attracted to each other. The way that large molecules interact in physical, chemical and biological applications is a direct consequence of the many tiny attractions of the smaller parts.

Introduction to Static Equilibrium Modeling (2 day)
Unrestricted Use

Rating
0.0 stars

This investigation will introduce students to systems, systems modeling and computational thinking using static equilibrium modeling with SageModeler. This (or the 5-day version of this activity) is a pre-requisite for Introduction to Dynamic Modeling. This 2-day version jumps into student modeling more quickly and relies more heavily on the teacher to scaffold concepts of systems, modeling, and SageModeler.

This investigation will introduce students to systems, systems modeling and computational thinking using static equilibrium modeling with SageModeler. This (or the 2-day version of this activity) is a pre-requisite for Introduction to Dynamic Modeling. This 5-day version has more scaffolding of the concepts of systems, modeling, and SageModeler built into the student activity, but still requires teacher guidance.

Is there life in space?
Only Sharing Permitted
CC BY-NC-ND
Rating
0.0 stars

There are billions of galaxies filled with billions of stars. Each star has the potential to have planets orbiting it. Does life exist on some of those planets? Explore the question, “Is there life in space?” Discover how scientists find planets and other astronomical bodies through the wobble (also known as Doppler spectroscopy or radial-velocity) and transit methods. Compare zones of habitability around different star types, discovering the zone of liquid water possibility around each star type. Explore how scientists use spectroscopy to learn about atmospheres on distant planets. You will not be able to answer the module's framing question at the end of the module, but you will be able to explain how scientists find distant planets and moons and how they determine whether those astronomical bodies could be habitable.

What farming practices can maintain good soil quality? Use the model to compare the effects of different landscapes, different crops, different tillage strategies, and climatic factors on soil quality and erosion rate. Watch the graphs to see how much topsoil is left in each zone and compare the erosion rates. Watch the soil quality indicator in the model to determine how different management plans affect soil quality.
